Symbols in BOM

I have searhed the forums and I have not found a defenitive answer to my problem, so here goes.

We use symbols in the quantity column to show feet inches pounds etc...

I am having difficulty maintaining links in the BOM when I try to add a symbol, click on cell and "Add Symbol".

In our assembly we use bulk tape and use say 4" as well as say 1.5' of lead wire.

Is there a way to maintain links in the BOM whilst adding these symbols?

Thanks!
